| Polarity mystery: Can you help me solve it? Hi Bryon,OK, so much for that theory. Well, I'm left at a total loss in trying to suggest an explanation. I can't envision how your observations could be related to interaction with room effects, as has been suggested. The effects of inverting the... | |
| Polarity mystery: Can you help me solve it? How would I know if my system had a DC offset?Hi Bryon,You would need a good multimeter, preferably a digital one that can measure dc voltage with a resolution adequate to read say a few millivolts (mv), or ten's of mv at most.You would power up t... | |
| First "real" TT... Most serious bids at eBay, on desirable items, are placed during the last 30 seconds of the auction. Bid amounts prior to that don't mean anything.Regards,-- Al | |
| Polarity mystery: Can you help me solve it? Hi Bryon,Gee, that's a tough one, assuming as you indicate that the effect is repeatable across a wide range of recordings, presumably ruling out the polarity of the recording as being a factor.The one possibility that occurs to me is that the out... | |
| The Hub: Made in the USA: First in a series Wonderful article, Bill. Thanks!Yes, the multi-chassis chrome-plated 1930's "radios" of E. H. Scott (no relation to the hifi manufacturer H. H. Scott, who came later), and McMurdo Silver, who was his chief competitor, can rightly be considered to ... | |
| Why power cable effect overall syste sound? I would suggest that the real question that should be addressed is not whether aftermarket power cords can make a difference relative to stock power cords (Grant has provided plausible, and in my view, valid explanations for that), but the reasons... | |
| Bryston BDA-1 DAC, any thoughts? Tamara -- Are you sure that the Technics has digital outputs? They made various models of 110 disk cd changers. I took a look at photos of some of them in eBay listings, and none of the ones I looked at had digital outputs.Re your question, though... | |
| Gain Question The vinyl sound is enjoyable at present but every once in a while there is that specific cut that you would just like to boost a little bit and I don't have that option. Which prompts a further thought. Records are cut at different levels. If you ... | |
| Gain Question From John Atkinson's measurements of the SLP-05:The SLP 05 offered slightly different maximum gains from the figures specified on Cary's website. However, the specified gain is different on the Specifications page10dB single-ended, 8dB, balanced... | |
| Gain Question 66db corresponds to a voltage gain of about 2000. 10db corresponds to a voltage gain of about 3.2. So 0.3mv from the cartridge will result in about 0.3 x 2000 x 3.2 = 1.9 volts into your power amp. That is roughly in the general area of input volt... | |
| why does digital volume control cause loss in info Excellent comments, Kirk. Thanks.Re your first point, to make sure its clear to others who may read this I'll add that the fundamental purpose of dither is to convert quantization distortion into low level analog-like broadband noise. Or even bett... | |
| why does digital volume control cause loss in info I took a quick look through the CS3310 datasheet. It looks like a pretty nice device, although I'd expect that designing with it, and achieving good results, would be a non-trivial challenge because of the presence of both digital and analog signa... | |
| why does digital volume control cause loss in info Shadorne: Thanks. Not sure, though, that it's fair to say that properly applied dither will necessarily make a digital volume control "as good as analog." It will certainly reduce the subjective objectionability of quantization noise. But I suspec... | |
| why does digital volume control cause loss in info Mapman has the right idea. I would slightly reword his statement as follows:"If all bits in each sample are required to represent a signal at the maximum possible volume, fewer bits will be available to represent each sample at lower volumes."The ... | |
| High Current SS amps with input impedance = 200K Mapman -- OK, I looked further and found the 45 amp peak current mentioned in this manual for the Ref1000M Version 1. It is not mentioned, though, in what I had been looking at, which was this manual for the Ref1000MkII.In any event, I think that ... |
